Answer:
B.
Step-by-step explanation:
We are told that the smallest object visible with our eyes is similar to the width of a piece of hair, which is meters wide.
Using an optical microscope, we can see items up to meters wide.
To find the objects we can see with our eyes are how much larger than the objects we can see with an optical microscope, we can set an equation as:
Using the exponent rule of quotient we will get,
Therefore, the objects we can see with our eyes are times larger than the objects we can see with an optical microscope and option B is the correct choice.
